The given points are (7, 2) and (-1, 0)

The slope of the line is given by

{tex}m=\frac{y_2-y_1}{x_2-x-1}{/tex}

Substituting the values

{tex}m=\frac{0-2}{-1-7}\\\\m=\frac{-2}{-8}\\\\m=\frac{1}{4}{/tex}

Point slope form of a line is given by

{tex}y-y_1=m(x-x_1)\\\\y-2=\frac{1}{4}(x-7)\\\\4y-8=x-7\\\\4y=x+1{/tex}
